UPDATE:

We tracked down the seller, 32-year-old Ian Baker, who said the tent belongs to a friend who was among dozens arrested last night while attempting to seize a Bank of America branch in San Francisco as part of the Occupy Wall Street protest.

His friend has since been released from police custody, but the tent is still under lock and key, Baker said.

"We're gonna try to get it back, but it really depends on the police department," he said. "If we can't, I'll contact the highest bidder to see what they want to do."

At any rate, Baker and his friends still plan to donate any proceeds to the Occupy Wall Street movement.
